因此，美国的警官在搜查住宅或个人时需要搜查令。排他性规则对社会及其成员有其自身的影响。它为社会成员提供了一个缓冲，并确保保护他们的私人事务(Kendall, 2016)。警察不能基于怀疑而入侵，在采取任何法律行动之前必须以搜查令的形式获得许可。采用和实施排除规则的主要目的是保护授予美国公民的宪法权利。第四修正案的主要表面效果是限制联邦官员的权力和权威。排除规则的实施限制了他们以法律的名义对一切不合理搜查的权力。美国宪法不允许警察进行任何非法没收，除非有明确的可能原因(Michela, 2008)。因此，排除规则在某种程度上维护了宪法权利，有助于安抚公民的神经，防止警察不必要的侵犯。换句话说，排除规则使人民免受警察的骚扰和暴行。
The exclusionary rule is used for regulation of police. However, there is confusion on its co-relation with the rest of the entire criminal justice system. The rule has been established as a separate power of principle vested with local governments. The warrant issuance process ensures privacy and confidentiality of an individual and prohibits police from invasion. In absence of exclusionary rule, the police would hardly have gone for issuance of search warrants. The legislative body would have used the found evidence at the event place as the main parameter for initiation of legal proceedings (Davis, 1997). Thus, evidences found near a person’s house, car or individuals with or without their permission would have possibility incriminate them. Initially, the rule was limited to federal government. However, with increase in crime rates, state governments were also under preview of the rule. In 1949, the Supreme Court refused application of exclusionary rule in case of Wolf versus Colorado. However, in legal battle of Mapp versus Ohio, the Supreme Court re-effected the rule in all fifty states of United States of America. The implications of the rule were location would not act as an obstacle for making searches by the police.
Therefore, a police officer in United States would require warrants for searching homes or individuals. The exclusionary rule has its own impact on the society and its members. It provides a cushion to the society members and ensures protection of their private matters (Kendall, 2016). The police cannot invade based on suspicion and has to obtain permission in the form of warrants before taking any legal action.The primary objective behind adoption and imposition of exclusionary rule was protection of constitutional rights granted to U.S. citizens. The prime facie effect of the Fourth Amendment was to limit the power and authority of Federal officials. The imposition of exclusionary rule restrained their power against all unreasonable searches in the name of law. The U.S. Constitution does not tolerate any illegal seizures made by the police unless there is some definite probable cause (Michela, 2008). Thus, exclusionary rule in a way upheld constitutional rights and helped to calm nerves of citizens against unnecessary encroachment from the police. In other words, exclusionary rule provided relief to the people from harassment and atrocities of the police.
